Ezra Parker, first lieutenant of Battery D, First Rhode Island Light Artillery, wrote a good post-war memoir on the fighting in and around Knoxville. Here he is on the fight at Campbell’s Station with the Rebel artillery:

“This battery we had often met in the East. It was one of the batteries of the Washington corps of artillery of New Orleans. This was an excellent battery. The enemy soon formed two strong lines of battle clear across the open country, about 200 yards apart. Light batteries came forward, halting in front, and took positions between the brigades. On the flanks the cavalry was seen in the open woodland. This scene was all spread out before us. In all our great battles, such as Manassas and Antietam, we rarely saw more than a fourth of a mile of our enemy’s line.”

A worthy memoir, indeed, from which we will hear more later.
